Congratulations on your pregnancy.
I was sorry to read about the loss of your first. My mother had three miscarriages and told me that it helped her to name the babies she lost.
I've had four children, and the hardest births for me were the first and third. The third was induced with pitocin, and I don't recommend that if you can possibly avoid it--my body was so not ready and that made labor harder. For the first and fourth I was very glad to be in a hospital because of complications with me (the first) and the baby (the fourth, and she's fine now). The second could have been done at home except for the epidural...the only one where I had an epidural, and by far my easiest delivery. It's worth noting that I'm a major wimp when it comes to pain, and didn't have much success with breathing techniques or anything else I learned. No advice for natural anything, as I was very conventional at the time all of my children were born. Though I can say that my mother had natural childbirth and did fine with all seven of her deliveries.
The one book I read was The Girlfriends' Guide To Pregnancy by Vicki Iovine. Not everything in it applied, but it's pretty lighthearted and covers things you might not expect, so I do recommend it. Aside from that I talked to my mom--the expert--and my sisters and friends who had been through it. The best advice usually comes from people; the books can't cover everything.
Pay attention to any cravings you have. During my pregnancies I mostly craved foods that were high in protein and calcium, both very important for my health and the babies' development. Remember that some fats are good, and fat is important for fetal development too. Don't overeat, but don't restrict yourself too much either. Remember to drink a lot of fluids, especially good old water. Rest when you need to, but be active if you feel like it.
For the first few weeks (if you are able to stay home for that time) sleep when the baby sleeps as much as possible. You'll both be recovering from the birth process, so don't push yourself too much.
You can do this!
